IMPROVEMENT. IN BEER-COOLERS.

Specification forming part of Letters Patent No. 154,979, datedSeptember 15, I814; application filed June 24, 1874.

To all whom it may concern:

Be it known that I, GEORGE BRANDES, of Cleveland, in the county of(Juyahoga and State of Ohio, have invented an Improved SwimmingBeer-Cooler, of which the follow ing is a specification:

This invention has for its object the cooling of beer in the vats bymeans of a floating or swimming bowl containing ice. It consists of asheet-metal bowl having a short upright flange, attached to the upperedge of which,

on the outside, is a hollow ring, forming an air-chamber, which insuresthe floating of the bowl.

Heretofore these swimmers have been made conical in form, and to keepthem in an upright position water has been placed in them and the icefloated in the water; but this has proved to be quite expensive, rapidlyconsuming the ice, and not so good a radiator of the cold. My improvedswimmers require no water, and by their form make a better radiation ofthe cold.

To enable others to fully understand my improvement, I will proceed todescribe the same in detail by the aid of the accompanying drawing, inwhich Figure I is a perspective view, and Fig. 2 is a vertical section,of my swimmer.

A, Figs. 1 and 2, represents a half-spherical sheet-metal bowl, havingan offset side, B, rising a short distance above the top edge; and tothe outside edge of the side B is attached a hollow ring, 0, solderedclose, and air-tight, and containing air, thus forming an air-chamber atthe top edge of the bowl, which prevents the bowl from sinking whenfilled almost full to the brim with ice or ice and Water.

This swimmer, floating about in the beer, rapidly cools the same by thedownward radiation of cold from its bottom.

I am aware that it is not new to make swimmin g beer-coolers of sheetmetal strengthened with Wire ribs, 850.

Having described my invention, I claim-- A beer-cooler, substantiallysuch as herein described, provided with a hollow ring or airchamber forthe purpose of increasing its buoyancy, as set forth.

GEORGE BRANDES.
